Description
Defines the switching frequency of the drive. Higher
switching frequency results in lower acoustic noise.
In multimotor systems, do not change the switching
frequency from the default value.
See also parameter 2607 SWITCH FREQ CTRL
section Switching frequency derating, I2N
Selects the control method for the switching frequency.
Selection has no effect if parameter
FREQ is 4 kHz.
Drive maximum current is automatically derated according
to the selected switching frequency (see parameter
SWITCH FREQ CTRL
derating, I2N on page 360) and adapted according to the
drive temperature.
It is recommended to use this selection when a specific
switching frequency is required with maximum performance.
